There are very few truly quiet places left in this country. There’s noise pollution even in the wildest, most remote national parks.

Gordon Hempton has been traveling to some of those last quiet places and he wants to protect them. He’s an Emmy-winning professional sound collector. He’s traveled the world to record everything from city streets to howler monkeys. He’s the author of One Square Inch of Silence: One Man’s Quest to Preserve Quiet. He’s joining me from Olympia National Park in Washington State.

You’ve said that you’ve found just 12 places so far in all of the U.S. where there’s an interval of at least 15 minutes without human noise. What do you think we’re missing out on if we lose those places?

HEMPTON: In a quiet place in nature not only are we listening to many, many square miles, but we are connecting, we are re-connecting, with where we come from, who we are and how our bodies have evolved to take it all in.

RW: A documentary has been made about you – called Soundtracker – and in it, the thing that struck me the most was when you talked about having to trust your gut feeling. You were in Sri Lanka, it was dark and you were recording…


(sound of Hempton’s Sri Lanka recording comes up under)


HEMPTON: Right, I learned a very important lesson that morning in the Sri Lanka rainforest of Sinharaja. And I was there to record morning bird song and that means getting up early, so I was walking into the forest, in the dark, and started to roll. And then my good feeling changed to panic. I could honor my panic and simply leave my equipment running, and so I walked away. Months later, I’m sitting in my Seattle studio reviewing the tape… I hear my footsteps disappear and moments later, there’s the guttural growl of the leopard.


(leopard growling)


RW: I have to tell you I found that sound to be terrifying!


HEMPTON: (laughs) Yeah, yeah, I know. I hate to think what would’ve happened if I’d remained there.


RW: So you’ve recorded all over the world for 30 years. How do you find these true quiet places?


HEMPTON: You know, I’ve been looking at Michigan. The very first thing I do, I look at the nighttime view of the United States, and I looked in this case at the nighttime view of Michigan. The upper half of Michigan was surprisingly dark. Then I went to the FAA chart to see all the airways that are charted and I could see that most of Michigan was covered. But there were two areas that were not. So I went to Google Earth and zoomed in on those places and I could see there were quite a few roads. But there were two locations: Manitou Island, particularly a site on that island that is Perch Lake. And also Lily Lake on Isle Royale National Park.


RW: So what can we do to protect these places?


HEMPTON: There’s one action we can all participate in to save the vanishing quiet places of this country. And that is to pass a single piece of legislation that will create for the very first time these areas off limits to all aircraft over our most pristine national parks.


RW: Gordon Hempton is a professional sound collector and the author of: One Square Inch of Silence: One Man’s Quest to Preserve Quiet. Thank you so much.


HEMPTON: Well, all right, thank you Rebecca.

New Air Pollution Rules

The Environmental Protection Agency has finalized new health standard for one kind of air pollution. Lester Graham reports:

In 1998 the American Lung Association sued the EPA to prod the agency to further reduce air pollutants that cause health problems. Among the pollutants was sulfur dioxide—known for causing acid rain. The primary sources of the pollutant are coal-burning power plants and other industrial plants. Sulfur dioxide emissions are capped at yearly limits, but this new rule also restricts short spikes in the emissions. Deborah Shprentz is a consultant to the American Lung Association. She says this new rule is a good first step to reduce the pollution.

“To protect the health of people, especially those with asthma and other respiratory conditions from breathing these short-term bursts of sulfur dioxide that can make them sick and send them to the hospital and even contribute to premature death.”

States will have a couple of years to comply with the new rule, but if it were put in place today, a projected 60 counties, mostly in the eastern half of the nation, would be out of compliance.

Past research has found that bacteria found in dirt can ease allergic reactions, reduce anxiety, and improve a person’s mood. Now, new research finds the bacteria might make us smarter. Mark Brush reports:

Researchers fed mice M. Vaccae bacteria and found the mice were twice as fast at navigating a maze.

Dorothy Matthews is an Associate Professor of Biology at Sage College in Troy, New York. She presented her research at a recent meeting of American Society for Microbiology. She says the bacteria are something we used to be exposed to more. Her comments were posted on the Society’s website:

“For most of our history we were hunter gatherers, rooting around in the soil, following the tracks of animals. It’s only been a hundred years or so ago, that we moved into cities and have become disassociated with nature.”

Researchers have found that M. Vaccae found in dirt can boost serotonin levels in the brains’ of the mice they studied. Serotonin can affect mood, appetite, memory and learning.

Sunscreen Safety Questioned

An environmental group is critical of the claims by many sunscreen manufacturers. They’re calling for better regulation of the industry by the government. Lester Graham reports:

Health experts say sunscreen should not be your first line of defense for protection from the sun. They recommend protective clothing and staying in the shade.

Once you’re out in the sun, though, health experts say sunscreen is a must.

But a new study by the Environmental Working Group found a lot of problems with sunscreens. The study says many contain suspect chemicals, some known as hormone disruptors. And Sonya Lunders says her group is skeptical about sunscreens that claim SPF protection of 50 and as high as 100.

“And we know that those products don’t offer a similar amount of protection from the sun-damaging UVA rays.”

Giving users a false sense of security about protection from sun damage.
Of the hundreds of sunscreens on the market, the group only recommends 39 of them on its website.

It blames the FDA for allowing a lot of confusing claims about sunscreens.

Transcript

This week, the U-S Environmental Protection Agency will release much-anticipated new rules limiting sulfur dioxide in the air. As Tanya Ott reports, it’s almost certain to result in years of legal battles:

When sulfur dioxide spews from smoke stacks and diesel engines it can cause
acid rain, but that’s just the first problem.

“It can cause asthma attacks in children. It can send people to hospital emergency rooms. It can even convert to other chemicals in the air that lead to premature death.”

Frank O’Donnell is president of the non-profit environmental group Clean Air Watch. He says existing rules, which have been around since the 1970s, have a loophole that allows high levels of sulfur dioxide over short periods of time. The new EPA rules will likely close that loophole and significantly restrict the amount allowed into the air.

The oil industry and coal-burning power plants have lobbied against the new rules. They don’t want to pay the billions of dollars it will cost to clean up their smoke stacks.

Safety Awards for Big Polluters

  • Some say that workplace safety awards promote complacency. (Photo courtesy of the NIEHS/DOE)

The companies associated with the two biggest accidents this year both recently got safety awards from the government. Lester Graham reports.

Transcript

The companies associated with the two biggest accidents this year both recently got safety awards from the government. Lester Graham reports.

The Mineral Management Service announced BP was a finalist for a safety award in May. Then, the Deepwater Horizon exploded, killed eleven men, and spilled –who knows how much– oil into the Gulf of Mexico.

The Mine Safety and Health Administration gave the coal company Massey Energy three safety awards last year. Then the Upper Big Branch Mine exploded. 29 miners died.

In an opinion piece in The Hill , The President of the Steelworkers union, Leo Gerard, argued those awards promote complacency– a sort of ‘see we’re already doing it.’

David Uhlmann is a law professor at the University of Michigan. He served for seven years as Chief of the Justice Department’s Environmental Crimes Section. He says awards can prod companies to do better… but…

“There’s always going to be some companies who cut corners, who put profits before safety, who put profits before their obligations to protect the environment.”

BP was to get its award in May. The safety awards ceremonies were postponed.

EPA’s Report on PBDEs

A new report from the Environmental Protection Agency links health problems to flame retardants. Lester Graham reports the EPA finds children are most at risk.

Transcript

A new report from the Environmental Protection Agency links health problems to flame retardants. Lester Graham reports the EPA finds children are most at risk.

Polybrominated diphenyl ethers, or PBDEs, are flame retardant chemicals used in all kinds of household consumer products. Sofas, computers, babies’ funiture. The report finds kids are getting a higher dose of PBDEs. That’s bad because the chemicals have been linked to many different developmental and reproductive health problems.

Arlene Blum is a chemist at the University of California Berkeley. She says the report notes PBDEs migrate from foams and plastics into household dust.

“Eighty to ninety percent of the human dose is from dust. So, toddlers, you know, they crawl in the dust, put their hands in their mouths. So, that’s why toddlers have such a high level at such a vulnerable time.”

The EPA report says the findings of many studies raise particular concerns about the health risks to children.

USDA Guidelines Questioned

  • Professor Paul Marantz says even a small error in the federal food guidelines can have a big public health impact. (Photo courtesy of the USDA)

Some people say the government is partly to blame for America’s obesity problem – because of the federal dietary guidelines. Julie Grant reports on efforts to improve how the government offers nutritional advise to Americans.

Transcript

Some people say the government is partly to blame for America’s obesity problem – because of the federal dietary guidelines. Julie Grant reports on efforts to improve how the government offers nutritional advise to Americans.

You’ve probably seen those colorful food pyramids they put out, the ones that tell you how many servings to have of each kind of food each day. Those recommendations are used by schools, nursing homes, and the federal food stamp program to design menus.

Robert Post works with the U.S. Department of Agriculture, which puts out the food pyramid.

“IT’S THE CORNERSTONE FOR BUILDING HEALTHY EATING PATTERNS. CHOOSING THE RIGHT AMOUNTS OF FRUITS, VEGETABLES, GRAINS, MILK PRODUCTS, AS WELL AS PROTEIN SOURCES SUCH AS MEAT AND BEANS.”

Post says people need to know how to get all the nutrients they need, without over-indulging in foods they don’t need.
That’s why the guidelines also set specific limits on things like salt and fat.

But some researchers think the guidelines actually have the potential to cause harm.

Paul Marantz is professor of epidemiology and population health at the Albert Einstein College of Medicine.
He doesn’t think the guidelines should give specific recommendations about how much fat and salt people should eat.

“THOSE SEEM TO CARRY PRECISION THAT IMPLIES THAT WE HAVE A GREATER DEPTH OF KNOWLEDGE THAN WE ACTUALLY DO, SO PICKING THESE NUMBERS AND REQUIRING THAT PEOPLE HUE TO THESE GUIDELINES IS A PROBLEM.”

Marantz says even a little bit of error in the food guidelines can have a big public health effects.

He and his colleagues wanted to find out the potential impact of past dietary guidelines.

They looked at 1995, when the nutritionists were telling people to avoid fat.

“MOST OF US REMEMBER IN THE OLD FOOD PYRAMID THAT MADE IT QUITE CLEAR THAT THE MOST IMPORTANT THING TO AVOID WAS FAT AND ONE COULD EAT GRAINS AND PASTA AND BREAT AND THE LIKE WITHOUT CONCERN.”

Marantz says Americans did eat more pasta and bread – that added lots of calories, and lots of weight.

His research, which was published in the American Journal of Preventive Medicine, found what Marantz calls a ‘strong correlation’ between the dietary guidelines against fat and obesity in Americans:

“CORRELATION IS BY NO MEANS CAUSATION. WE CANNOT INFER FROM THIS THAT IT WAS BECAUSE OF DIETARY GUIDELINES THAT WE ARE EXPERIENCING THE EPIDEMIC OF OVERWEIGHT AND OBESITY. BUT THE CONNECTION IS STRONG.”

Marantz wants the government to give general advice for healthy eating, but not specific guidelines. He gives the example of sodium. Marantz says no one really knows how much salt is appropriate for each person. But there’s a push to put specific limits on sodium in the new guidelines.

Robert Post of the USDA says anything that gets into the 2010 recommendations will be based on what he calls the Gold Standard of scientific evidence. He says a committee of nutritional experts has been meeting for two years to create the new guidelines…

“WE CAN BE ASSURED THROUGH THIS VERY INTENSIVE REVIEW OF SCIENCE AND THE WEIGHT OF THE EVIDENCE IT PROVIDES THAT THE CURRENT ADVISE ON CARBOHYDRATES FOR EXAMPLE IS BASED ON THE LATEST RESEARCH.”

Post says any recommendations for fat and sodium will also be based on the preponderance of current science. The committee is expected to make its recommendations this summer, and new dietary guidelines should be published by the end of the year.

Researchers tell us one way to stay trim is to walk more often.

But that’s hard in some neighborhoods – maybe sidewalks are bad or there are no stores to walk to.

Shawn Allee found one researcher who thinks what really stops us … is actually in our heads.

Dr. Tanya Berry researches physical activity, and she surveyed people living in Edmonton, Canada.

She calculated how trim or fat they were, then she logged details about their neighborhoods, things like how many stores are nearby and how many cars pass through the area.
Berry says the thing that mattered most, and kept people from walking was a subjective feeling that there are too many cars on the street.

“There was too much traffic in their neighborhoods, it made it difficult to walk, so they chose to jump in their cars and contribute to the traffic problem.”

Berry says her research team will look at how buildings and streets can be designed to make pedestrians feel there’s less traffic than there actually is, and maybe feel more comfortable walking down the street.

Companies Keep Cosmetics Chemicals Secret

  • Researchers have found undisclosed chemicals in a variety of products, from perfume to floor polish. (Photo courtesy of Escape(d) CC-2.0)

When you use cosmetics or cleaning products, you might assume that the government has checked out the ingredients and has deemed them safe. But Julie Grant reports – that’s not the case. Companies don’t even have disclose everything that’s in their products.

Transcript

When you use cosmetics or cleaning products, you might assume that the government has checked out the ingredients and has deemed them safe. But Julie Grant reports – that’s not the case. Companies don’t even have disclose everything that’s in their products.

The Campaign for Safe Cosmetics wants the labels on cosmetics to reflect all the ingredients in a product. But spokesperson Stacy Malkan says that’s not what’s happening. The Campaign recently sent 17 brands of perfumes and body sprays to an independent lab.

“We found in these products an average of 14 hidden chemicals that were not on the labels that the lab was able to detect.”

Malkan says some of those hidden chemicals have been associated with asthma and headaches, while others are hormone-disruptors, linked to sperm damage, thyroid problems, and even cancer. Malkan says there’s a reason companies don’t put those chemicals on the labels: they don’t have to.

“It is required that companies list the chemicals in their products, except that if they are part of the fragrance. So there’s a huge loophole in the federal law that allows companies to keep secret the chemicals in fragrances.”

And this loophole exists for more than just for perfumes.
Malkan says they have things like children’s bubble bath can create toxic contaminants. And researchers have found un-disclosed chemicals in nearly all brands of cleaning products – things such as dishwashing soap, floor polish, and air fresheners.

“If a chemical is found in a product, it doesn’t mean that the product is toxic or hazardous.”

Gretchen Shaefer is spokesperson for the Consumer Specialty Products Association, which represents the makers of cleaning products. She says companies are required to list anything that’s hazardous on the label.

As more consumers ask for additional information, she says manufacturers are providing more about their chemical formulas. But Schaefer says most are not willing to disclose the trade secrets of their fragrances:

“It is the fragrance that makes those products unique. And that’s why protecting those fragrance formulas are absolutely critical to the manufacturers of the overall product.”

That’s also true when it comes to companies that make cosmetics and perfumes. The trade group representing the cosmetics industry says that new study, the one that found 14 un-disclosed chemicals in the top perfumes and colognes, is misusing the information. The Personal Care Products Association says the chemicals in question are only a concern at very high levels. But the study doesn’t report the levels of these chemicals.

The Campaign for Safe Cosmetics says most of the chemicals it found in fragrances have not even been assessed for safety.

Ann Steinemann is an environmental engineering professor at the University of Washington, and has studied hundreds of cleaning products. She says nearly all brands on the market, even those labeled green products, contain undisclosed carcinogens – which are considered hazardous by the Environmental Protection Agency:

“According to the EPA, things that are classified as carcinogens have no safe exposure level. There is no safe exposure level. Even one molecule cannot be considered safe.”

Bills have been introduced in both the U.S. House and Senate to change labeling laws on things like cleaning products. And the EPA has recently classified some of the chemicals found in fragrances as chemicals of concern. Advocates for improved labeling and safer ingredients advise consumers to use fewer products with fragrances.
